That’s what city attorneys are asking in seeking to quash a lawsuit that claims the property tax system discriminates against tens of thousands of largely minority homeowners.

The suit, de Blasio administration lawyers say, doesn’t identify a single person affected by the supposedly unfair policies.

The Manhattan Supreme Court case was filed in April by a group called Tax Equity Now NY, which is comprised of the NAACP, the Black Institute and unspecified “landlords and homeowners.”

In papers filed late Friday, the city says the organization doesn’t have standing to sue.

“TENNY does not claim to own any property, to have paid any taxes, or to have been injured by the city’s administration of the tax laws,” lead city lawyer Vincent D’Orazio says in court papers.

The group argues that unnamed owners of multi-million dollar homes in majority white neighborhoods like tony Park Slope pay a small fraction of the tax rate shouldered by largely black population of working class Jamaica, Queens.

On average minority residents pay $844 more in real estate taxes each year compared to homeowners in majority-white districts, the suit says.

Property tax is the city’s largest source of revenue, bringing in an expected $24 billion this year.

Martha Stark, a director at Tax Equity Now NY, said that the city should “focus on finding a solution to the fundamental unfairness and irrationality of the system” instead of “spending time and money to stop” the suit.
